Enterprise Security for AI Tools

Security Gateway for AI Tools

SolonGate sits between AI agents and their tools to enforce policy, validate inputs, and guard against prompt injection, over-permissioning, and data leakage via AI tool calls.

How the AI Tool Security Proxy Works

Zero-trust security layer between AI agents and tools — every tool call is intercepted, validated, and logged

Every tool call is validated against policy rules defining granular scope permissions. Block filesystem access outside /logs, restrict database tables, and control API endpoints with declarative rules.

Security Architecture

Five-Step Protection Pipeline

Every AI tool call passes through five security layers before reaching the real server

1

Schema Validation

Strict JSON schema enforcement rejects malformed or extra fields

  • Type checking & field validation
  • Rejects unknown properties
  • Enforces required fields
2

Policy Check

Action + scope permissions verified against declared policies

  • Role-based access control
  • Scope verification
  • Permission enforcement
3

Input Guard

Path traversal, wildcards, and shell characters blocked

  • Injection prevention
  • Path traversal blocking
  • Character sanitization
4

Tool Execution

Allowed request forwarded to tool server with audit logging

  • Secure tool invocation
  • Full audit trail
  • Error handling
5

Output Guard

Secrets and PII redacted before returning to agent

  • Secret detection & masking
  • PII redaction
  • Safe response delivery

Frequently Asked Questions

What is SolonGate?
SolonGate is a security gateway that sits between AI agents (like Claude, GPT, Gemini) and the tools they use (file system, shell, APIs). It enforces policies, detects prompt injection, and logs every action for audit.
How does SolonGate work?
SolonGate runs as a security proxy between AI agents and their tools. It intercepts every tool call, runs it through a 5-step security pipeline (rate limiting, input guard, policy evaluation, prompt injection detection, and AI Judge), then forwards safe calls to the real server.
How does SolonGate connect to AI tools?
SolonGate acts as a transparent proxy between your AI client and the tools it uses. It supports stdio, SSE, and HTTP transports — so it works with any AI platform without requiring changes to your tools or workflow.
Does SolonGate slow down AI tools?
The rule-based checks (rate limiting, input guard, policy evaluation) add minimal overhead. The optional ML-based prompt injection stages (embedding + DeBERTa classifier) require a one-time model download but run locally and are cached after that.
What attacks does SolonGate prevent?
Prompt injection (instruction override, role hijacking, delimiter injection, jailbreaks), path traversal, shell injection, SSRF, SQL injection, data exfiltration, wildcard abuse, boundary escape, and high-entropy encoded payloads.
Do I need to change my existing setup?
No. SolonGate works as a drop-in security proxy. Point your AI client to SolonGate instead of the real server, and SolonGate forwards to the upstream. One command: npx @solongate/proxy -- your-server.
Is SolonGate free?
SolonGate has a free tier with 500 tool audits per month and 1 policy. Pro starts at $20/month with 5,000 audits and unlimited policies. Enterprise plans offer unlimited everything with SLA.
What AI platforms are supported?
Claude Code, Gemini CLI, OpenClaw, and any AI platform that uses MCP tool calls. SolonGate is protocol-level, not vendor-specific.
